FRICTION-GEAR.

SPECIFICATION forming part of Letters Patent No. 751,878, dated February 9, 1904.

Original application filed October 29, 1901, Serial No. 80,410. Divided and this application filed March 11, 1903. Serial No. 147,270- No model.)

1'0 (M whom it may concern.-

Be it known that I, SAMUEL C. SPANGLER, a citizen of the'United States, and a resident of Clyde. in the county of Grant and Territory of Oklahoma, have invented a new and Improved Friction-Gear, of which the following is a full, clear, and exact description.

This invention relates to a gear by which rotary movement may be transmitted from a IO single driver to a plurality of driven elements in either direction.

Briefly stated, the apparatus comprises a driving-shaft having two spaced gear-disks fast thereon, the driven element or elements 5 having gears set between the gear-disks and means for moving the gears of the driven elements into engagement with either of the disks, whereby to drive the driven elements in either direction.

The invention is applicable to many purposes, but as here illustrated it is best adapted to my pitching apparatus, which forms the subject of my copending application, Serial No. 80,4:10, filed October 29, 1901.

2 5 This specification is an exact description of one example of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a section of the invention on the line 1 1 of Fig. 2, and Fig. 2 is a plan view of the invention. 3 5 (4 indicates a frame, and 6 indicates the primary movement shaft, which latter is fitted with agear b,(see dotted lines,Fig. 2,) in mesh with a gear 0 on a vertical shaft (Z. This shaft (Z is mounted in the frame a, and in an overhanging arm 6, which is fastened on the frame, as shown.

f and g indicate the friction-gear disks, which are keyed or otherwise fastened on the shaft (Z and spaced from each other, as shown, the arm 0 projecting between them.

it indicates the driven elements or shafts, here shown to be three in number. To these shafts h are connected universal joints it, which are also connected to short shafts if. The short shafts 7L2 extend between the disks 5 f and g and carry the friction-gears c, which are of such diameter that they may stand out of contact with either gear, as shown in Fig. 1, and through the action of the joints it these gears 2 may be engaged with either of the disks f and g, and thus the shafts It may be allowed to rest or be driven in either direction at will. Oollars Z; are arranged loosely on the shafts if, and to these collars are fastened boxes 70, fastened to or forming parts of vertical rods k Said rods are held to slide longitudinally in the frame a and are connected at their lower ends to levers 10 which are fulcrumed under the shaft cl and have links If attached to their other ends.

indicates hand-levers, which are of elbow form and connected at their short arms to the links the long arms standing vertically as handles. Springs is are fastened to the frame a and bear against plane portions k of the le- 7 vers at points opposite their fulcra, these springs serving to hold the levers normally in vertical position.

By swinging the levers k as indicated by the dotted lines in Fig. 1 the gears i may be 75 engaged with either gear f and g, as desired, and upon releasing the levers they are thrown back to inactive position by the springs if.

It will be observed that this arrangement gives the operator complete control over the various shafts h, allowing them to be turned at will in either direction.

Various changes in the form, proportions, and minor details of my invention may be resorted to without departing from the spirit 5 and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent" 9 1. The combination of a revoluble member having two surfaces spaced from each other, a revoluble shaft, a second shaft having universal connection with-the first-named shaft,

' duced between the two surfaces of the said revoluble member, a box in which the secondnamed shaft is revoluble, a rod attached to the box, a guide in which the rod is reciprocal,

and means for actuating the rod, said means comprisinga lever connected to one end of the rod, a link connected to the other end of the lever, a hand-lever connected to the link, said hand-lever being bent and having a plane portion adjacent to its elbow, and a spring member engaging said plane portion, for the purpose specified.

2. The combination with a framing, of an overhanging arm mounted thereon, connected friction-disks spaced from each other and between which the arm projects, whereby revolubly to mount the disks, means for driving said disks as a unit, a shaft, a second shaft having universal connection therewith, a friction-wheel attached to the second shaft and "operating the rod.

3. The combination with a framing, of an overhanging arm mounted thereon, connected friction-disks spaced apart from each other 'and between which the arm projects, said arm mounting the axles of the disks to permit the rotation thereof, means for driving said disks as a unit, a friction-wheel seated between the disks, and means for adjustably mounting the frictionwheel and transmitting the movement thereof, said wheel being capable by its adjustment, of engaging either disk.

4. In a friction-gear,tl1e combination of two disks spaced apart and mounted to turn as a unit, means for driving the disks, a revoluble shaft, a shaft-section having universal connection with one end of the revoluble shaft and projected essentially longitudinally beyond the shaft, said shaft being capable of swinging around the center of said connection and being projected between the said disks, a friction wheel attached to the shaft between the disks, for the purpose specified, a collar mounted loosely on the shaft-section, a box having pivotal connection with the collar, a rod attached to the box, a guide for the rod permitting the same to move longitudinally, and means for so moving the rod.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

SAMUEL C. SPANGLER.
